چکیده

Earned Value Management (EVM) is a technique that provides decision makers with efficient control, analysis and monitoring of the performance and progress of a project to prevent delays and cost overruns. Earned Schedule (ES), as an extension of EVM, is introduced to deal with the problems of EVM schedule performance indicators. Using statistical quality control principles has proved to enhance the efficiency of EVM and ES. In previous studies, schedule and cost indicators were considered as independent indices, and thus the relationship between these two variables was ignored. The failure to take into account the dependency between dependent parameters can result in unrealistic and misleading results. Therefore, in the proposed approach, the relationship between two basic elements of EVM and ES, i.e. time and cost is also considered in order to more precisely analyze the results obtained from these methods. Multivariate quality control chart (MQCC) are applied alongside univariate quality control charts (UQCCs) for analyzing, investigating, managing and monitoring projects to improve the capability, accuracy and efficiency of EVM and ES. Furthermore, to show the applicability and superiority of the proposed approach, it is applied to a construction project case study.
